Description

Technical Field

[0001] This utility model relates to the field of construction tools, and in particular to a step-by-step tensioner for construction. Background Technology

[0002] Step-by-step clamping is a new type of construction equipment that replaces the traditional wire binding method, screw rod method, and fixed ring and plug method. It is used to clamp steel pipes and formwork. It consists of a hook-shaped clamping rod and a movable clamping head. The movable clamping head is fitted onto the hook-shaped clamping rod. In order to prevent the movable clamping head from easily falling off the outside of the hook-shaped clamping rod, an anti-detachment structure is usually installed at the end of the hook-shaped clamping rod to block the movable clamping head and prevent it from falling off the outside of the hook-shaped clamping rod.

[0003] When the movable locking head is retracted, it slides freely on the hook-shaped locking rod. This inevitably leads to collisions with the anti-detachment block. Prolonged collisions can easily damage the movable locking head and the anti-detachment block. Utility Model Content

[0004] The purpose of this utility model is to provide a step-by-step tightening device for building construction in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A step-by-step fastener for building construction includes a hook-shaped clamp and a movable clamp head. The tail end of the hook-shaped clamp is provided with an anti-detachment block. The anti-detachment block is fixedly installed to the hook-shaped clamp by a positioning bolt. The surface of the anti-detachment block is provided with a fixing strap for fixing the movable clamp head. Both the hook-shaped clamp 1 and the movable clamp head 2 are movably connected to the fixing strap 5. The surface of the anti-detachment block is also provided with a fixing head. The fixing strap and the fixing head are used in conjunction.

[0007] As a further description of the above technical solution:

[0008] The fixing belt consists of a belt body and a belt head, and a fixing hole is formed in the belt head. As a further description of the above technical solution:

[0009] As a further description of the above technical solution:

[0010] The fixing head consists of a mounting post and a limiting head. The limiting head is hemispherical and its radius is larger than that of the mounting post.

[0011] As a further description of the above technical solution:

[0012] The radius of the fixing hole is the same as the radius of the mounting post, and the head is also provided with a cross hole that corresponds to the fixing hole.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] In this invention, the movable clamp head can be fixed by the cooperation of the fixing strap and the fixing head, so as to prevent it from sliding freely onto the hook-shaped clamp rod when not in use and colliding with the anti-detachment block and causing damage. The fixing method is simple and easy to operate, and the fixing can be quickly removed without affecting the use of the step-by-step clamping mechanism, making it convenient to operate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5As shown, a step-by-step fastener for building construction is a construction tool, including a hook-shaped clamp 1 and a movable clamp head 2. The tail end of the hook-shaped clamp 1 is provided with an anti-detachment block 3, which is fixedly installed to the hook-shaped clamp 1 by a positioning bolt 4. The surface of the anti-detachment block 3 is provided with a fixing band 5 for fixing the movable clamp head 2. Both the hook-shaped clamp 1 and the movable clamp head 2 are movably connected to the fixing band 5. The surface of the anti-detachment block 3 is also provided with a fixing head 6, which is used in conjunction with the fixing band 5. The fixing band 5 consists of a band body 51 and a band head 52, with a fixing hole 53 inside the band head 52. The fixing head 6 consists of a mounting post 61 and a limiting head 62. The limiting head 62 is hemispherical and its radius is larger than that of the mounting post 61. The radius of the fixing hole 53 is the same as that of the mounting post 61. The head 52 also has a cross hole that corresponds to the fixing hole 53. The fixing head 6 can fix the movable clamp 2 by using the fixing band 5 to prevent it from sliding freely onto the hook-shaped clamp 1 when not in use and colliding with the anti-detachment block 3, causing damage. The fixing method is simple and easy to operate, and the unfixing is also quick. It does not affect the step-by-step clamping use and has good operation convenience.

[0023] Working principle: After the step-by-step tightening is finished, remove the end 52 of the fixed strap 5 from the fixed head 6, then wrap the strap body 51 around the movable clamp 2 so that the movable clamp 2 is close to the anti-detachment block 3. Then, re-insert the removed end 52 into the mounting post 61 of the fixed head 6. After the step-by-step tightening is needed, remove the end 52 of the fixed strap 5 from the fixed head 6, and then loosen the strap on the movable clamp 2 so that the movable clamp 2 can move again in the hook-shaped clamp 1.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
